Cybersecurity researchers at Fortinet observed in 2024 that the surge in stolen login credentials is being actively marketed on the dark web. More than 1.7 billion usernames and passwords were stolen, not from old data leaks, but by hackers who were actively spying on people’s computers or phones while they were being used.
Here’s everything broken down into clear, simple pointers, covering what infostealers are, how they work, and five detailed steps to protect yourself.
How Infostealers Spread?
Phishing emails are super common, they are fake messages that try to trick you into clicking a bad link or file. Then there are fake browser extensions that seem useful but actually steal your data secretly. Another big one is fake software or “cracked” apps, you think you’re getting free stuff or cheats, but you end up installing malware instead.
What They Steal and Why It’s Dangerous?
Infostealer malware steals stuff from your browser like saved passwords, autofill info, cookies, and session tokens. The scary part is that with session tokens and cookies, hackers can log into your accounts without your password or even the 2FA code. They can also grab other things like FTP logins, cloud accounts, and digital wallet keys, basically, all the important stuff you don’t want anyone else to have.Once infostealers collect your data, they upload it to command-and-control servers controlled by cybercriminals. This stolen data, also called “logs,” is then sold by initial access brokers, middlemen who trade these logs with other criminals. The data is often used in bigger attacks, like ransomware. The scale of the problem is huge, with a 500% rise in stolen credential logs in just one year, according to Fortinet’s 2025 report. Some of the most common and dangerous infostealers include RedLine, Vidar, and Raccoon. Today, stolen data is sold like regular products, where buyers can purchase VPN or admin logins with region-specific pricing.
Now How Can You Avoid Begin One Of The Target, Here Are 5 Simple Tips:
1) Don’t save credentials in your browser. A password manager keeps all your logins in one secure vault. Many include breach-warning tools to tell you if any password is exposed.
2) Add a second step (code from an app, text message or biometric scan). Even if someone steals your password, they can’t log in without that extra code. Turn on 2FA for email, banking, social media and work accounts.
3) Only download apps and files from official websites or app stores. Don’t click links in unexpected emails, hover over links to check the real address.
4) Turn on automatic updates for your operating system and critical programs.
5) Consider a Personal Data Removal Service as they help scrub your name, email, phone and address from data-broker sites.
